Question

Image text transcribed for accessibility:A Wheatstone bridge circuit is used with a resistive based sensor (for example, a strain gauge) in the circuit shown below. The resistance of the sensor is comprised of two terms such that Rg = Ro + where Ro = 2kOhm is the nominal (or no-load) value of the sensor is a desired signal to be measured which is assumed to be constant. At full load the value of is given by = plusminus0.1 . Ro. Determine the value of the resistor R2 such that under the full load condition ( = plusminus0.1 Ro) the value of the output voltage (in steady-state) is equal to vo = plusminus5V (assume ideal op-amp behavior).
